WaterWeed Simulation

Introduction:In this simulation, you will be looking at the production of oxygen as a plant photosynthesizes. This procedure can be accomplished by placing elodea plants in water with baking soda to provide carbon. The plant can then be exposed to varying intensities and colors of light and acidity. The oxygen is measured by the number of bubbles produced by the plant. This simulator addresses three factors that influence the rate of photosynthesis. And these three factors are Carbon dioxide availability, light intensity, and light color.

1. Based on the data, what color of light results in the fastest rateof photosynthesis? Propose an explanation for these results. Colorless light results in the fastest rate of photosynthesis. The more bubbles we see, higher amounts of photosynthesis is happening.

Affect of Light Level on Photosynthesis: Set the simulator to colorless light CO2 level to 6.0. Make adjustments to the level of light to complete the data table.

Light Levels:1.02.03.04.05.06.07.08.09.010.0Number of Bubbles (Light: Colorless & CO2: 6.0):4, 8, 11, 14, 17, 21 ,24, 2627302. Based on the data, what light level results in the fastest rate of photosynthesis? Propose an explanation for these results. Based on the data, 10.0 results is the fastest rate of photosynthesis. The more bubbles we see, the more photosynthesis is happening at that moment.
